HOPPER GATE.

Application filed June 4, 1926. Serial No. 113,629.

This invention relates to gates for gravity discharge hoppers, more particularly to hoppers such as used beneath boilers in power houses to receive ashes, or in other instances of hoppers in which hot materials are collected and quenched with water or other liquids incident to disposal.

The present invention is concerned with drainage of the quenching water continuously seeping from the hoppers when the gates are closed, and is directed toward preventing leakage around the gate openings. This end I attain by provision of an efficient seal between the stationary and movable members of the gate, maintained, as hereinafter fully explained, through cooperation of splash deflecting guards on one of said members with discharge flow channels on the other.

With reference to the drawings, Fig. I is a rear view of a hopper gate conveniently embodying my invention, a portion being broken away at the upper right hand end of this illustration to show certain important details to better advantage; and,

Fig. 11 is an elevation of the organization as viewed from the left hand side of- Fig. 1, parts being also broken awayin this instance-for a purpose analogous to that mentioned in connection with the previous illustration.

The gate herein shown comprises an outlet member 10 in the form of a rectangular frame provided at the top with a perimetric flange 11 for convenience in bolting it about the discharge opening of the hopper shown at H in Fig. II. The opposite end walls -12 of the outlet member 10 afford bearings 13 to take the pivot trunnionslt of the movable closure member 15 of the gate. The trunnions 1 1, it will be observed, are integral projections of sectoral side spiders 16 which jointly support between them the arcuate portion 17 that is curved concentrically with regard to the pivotal axis. The part 17 is equipped with a renewable plate 18 that serves as the closure surface across the upper and lower walls 19, 20 of the outlet member 10. From Fig. 11 it will be noted that the plate 18 is spaced somewhat from the part 17 to provide an interspace 21 for passage of air for cooling purposes, said member 17 being perforatedas at 22 in Fig. I-

to promote local circulation of the air and thereby facilitate dissipation of heat imparted to the metal by incandescent ashes in the hopper H. The-sectoral side members 16, 16 of the movable member 15 are ex-.

tended rearward as at 23 for attachment of counter-balancing weights 24. To'one of these weights 2 1 is secured an arm 25 with a pivoted handle 26 enablingmanual opening of the gate through clockwise movement of the member 15 about the axis of its pivot trunnions 14. The water draining from the gate is received in a gutter 27 which slopes toward the observer in Fig. II, and at the near end has a spout 28 whereby the water 1s conducted into a gutter 29 for final disposal through a vertical drain conduit 30. The trough 27 is pivotally connected to the fixed outlet member 10 at 31, see Fig. II, and coupled by a link rod 32 with one of the arms 23 of the movable member 15. Thus, when the gate is opened, the trough 27 is concurrently swung out of the way of the material discharging through the hopper outlet.

The general structure thus far described forms the subject matter of a separate application simultaneously filed herewith in the name of William J. Burnett, and is referred to merely by way of elucidating the novel features of the present invention now to be described. Internally of its opposite sides 12 the outlet member 10 is provided with inwardly projecting arcuate guards 35 with down-turned lips 36 shown to best advan tage in Fig. I. These guards 35 are concentric with the pivot axis of the gate 15 and overhang channels 37 of U shape cross sections extending peripherally about the curved edges of the sectoral spiders 16, 16. When the gate 15 is in the closed position shown in the drawings, it will be apparent that the quenching water seeping from the hopper H and escaping along the side edges of the closure plate 18is caught by the inwardly projecting guards 35 of the outlet member 10 and thereby first deflected inward and then directed downward to drain into the peripheral channels 37 of the movable gate member 15, the water so caught being conducted downward through said channels 37 and discharged into the trough 27. By this arrangement an eflicient seal is afforded against escape of water in the intervals between the side edges of the movable gate member 15 and the contiguous Walls of the outlet member 10.

Having thus described my invention, I claim:

1. A hopper gate of the character described comprising a stationary outlet member and a closure member of arcuate formation movable Within the outlet member, the outlet member having, at opposite sides, arcuate guards to deflect spill of quenching water, seeping from the hopper into U-section flow discharge channels of the movable member. 7

V 2. A hopper gate of the character described comprising a stationary outlet member and a closure member of arcuate formation movable Within theoutlet member, said outlet member having at opposite internal sides I arcuately directed guards with down-turned lips to inwardly deflect spill of quenching Water, seeping from the hopper, into flow discharge channels at contiguous outer sldes of the movable member aforesald.

3. A hopper gate of the character described comprising a stationary outlet member and a closure member of arcuate formation pivoted for swinging movement Within the outlet member, said outlet member having inwardly proj ecting arcuate guards With downturned lips internally of its opposite sides and concentric With the pivot axis, to inwardly deflect spill of the quenching Water, seeping from the hopper, into concentric flow discharge U-section channels at contiguous outer sides of the closure member aforesaid.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this 6th day of May, 1926.
